x86: Move CPU init to before spl_init()

Browse source 
At present we call spl_init() before identifying the CPU. This is not a
good idea - e.g. if bootstage is enabled then it will try to set up the
timer which works better if the CPU is identified.

Put explicit code at each entry pointer to identify the CPU.
